Sebastian Vettel was left pleased by Kimi Raikkonen's contract extension at Ferrari, insisting the two have the "least ego problems" within the Formula One paddock. 

Raikkonen's contract was set to run out at the end of the 2016 season, but the Finn was able to agree to a one-year extension with the Italian manufacturer. 

The 2007 world champion is set for his 100th race with Ferrari at Sunday's British Grand Prix, but the 36-year-old has failed to taste an F1 victory in over three years. 

However, Vettel believes keeping Raikkonen was the right move, as the two share a healthy relationship as Ferrari team-mates. 

"It's the right thing to do," four-time F1 champion Vettel told Sky Sports. "We are both pushing very hard. 

"Our primary target is to catch the leaders, Mercedes, and there's plenty of work ahead of us. I think it's important, there's been a lot of talk, and it now goes quiet.

"Probably Kimi and myself have the least ego problems in the whole paddock, which I think is good for the team. 

"We are working in the same direction and on the track we try to race hard - as we've shown in the past in the races where we have raced for position - but that's normal.

"Outside of the car there is no problem."

However, Jenson Button was left a little confused with Vettel's sentiments, believing he and McLaren team-mate Fernando Alonso share a special bond of their own. 

"Come again?!" Button posted via Twitter as he quoted Vettel's comments.
